LinkedIn Post Size, Algorithm & Content Ideas (2026 Guide)

Every current LinkedIn image, banner, video and carousel size in one table, an honest read on how the algorithm actually ranks posts, and ten content ideas built specifically for B2B engagement — not a repeat of our general LinkedIn strategy guide.

Quick answer: The most common LinkedIn post image size is 1200×627px (1.91:1). A company Page cover is 1128×191px, a personal profile banner is 1584×396px, and a profile photo needs at least 400×400px. Native video does best at 1:1 or 4:5 under three minutes, and document (carousel) posts perform best at a 4:5 or 1:1 ratio.

This page is the sizes-and-content spoke of our social media marketing guide — if you need the fuller organic strategy (posting cadence, profile setup, company Page basics), our LinkedIn marketing guide covers that in depth. What follows here is narrower and more practical: the exact current specs, what the algorithm actually rewards, and content ideas you can use this week.

Current LinkedIn Post and Banner Sizes (2026)

LinkedIn crops and compresses images that don't match its expected ratios, so getting the size right the first time avoids an awkward crop on mobile.

Post typeRecommended sizeNotes
Single image post (feed)1200 × 627 px (1.91:1)LinkedIn's feed crops toward roughly this ratio; a square 1:1 image also displays cleanly on mobile.
Company Page cover/banner1128 × 191 pxSits behind your Page name and logo — keep important text out of the bottom third, which the info panel overlaps on mobile.
Personal profile banner1584 × 396 pxDisplays behind your profile photo; avoid placing text near the edges, since it gets cropped differently across devices.
Profile photo400 × 400 px minimum, squareDisplays circular. A higher-resolution upload (up to 800×800px) holds up better when LinkedIn shows it large.
Video post (native, feed)1:1 or 4:5 vertical; 16:9 landscape also supportedKeep it under 3 minutes for feed reach — longer uploads are allowed, but attention drops hard past that point.
Document / carousel post4:5 or 1:1, PDF up to 300 pagesLinkedIn's native "document" format — one idea per page or slide tends to outperform a single static image post.
LinkedIn ad creativeVaries by objective and formatFull ad specs, formats and budgets are covered in our LinkedIn Ads for B2B guide, not repeated here.

Specs above are current as of 2026. LinkedIn does update image and video requirements periodically without much notice — for anything high-stakes, double-check against Campaign Manager or LinkedIn's own help pages before you send.

How the LinkedIn Algorithm Works in 2026

Early engagement windowDwell timeComments > reactions

LinkedIn has never published its exact ranking formula, and anyone who tells you they've fully reverse-engineered it is overstating what's knowable. What follows is drawn from LinkedIn's own public statements and consistent, widely-observed patterns — treat it as directional, not a guaranteed playbook.

  • Early engagement velocity matters most. LinkedIn tests a post with a small slice of your network first, then decides whether to widen distribution based on how that slice reacts — mostly in the first 60–90 minutes. A slow start is hard to recover from later.
  • Dwell time counts as a real signal. How long someone actually pauses on your post — reading a document, watching a video, sitting with a text post — appears to weigh more than a passive scroll-past like or view.
  • Comments are weighted above reactions. LinkedIn has said publicly that a comment, especially one the original poster replies to, signals more than a like or a "celebrate" tap. Asking a genuine question in your post is a simple way to invite that.
  • Native formats tend to travel further than outbound links. Posts that keep people on LinkedIn — documents, native video, plain text — often see more reach than posts linking off-platform. LinkedIn has said the "link in the first comment" workaround doesn't move the needle as much as people assume, but the honest answer is that this varies by account, so it's worth testing on your own Page rather than trusting either claim blindly.
  • Document and carousel posts often get an extra push. Multi-page native documents tend to earn longer dwell time than a static image, and LinkedIn's distribution appears to reward that — though this is an observed pattern, not a confirmed permanent algorithm rule.

One thing worth clearing up: LinkedIn retired the separate "Creator Mode" toggle in 2024. Its main benefit — letting anyone follow your posts publicly, not just people you've connected with — is now a setting available on every profile. If you're still looking for a Creator Mode switch that no longer exists, check your profile's "Follow" setting instead.

10 LinkedIn Post Ideas That Actually Work for B2B

The 2026 algorithm rewards genuine engagement over polish, which is good news — you don't need a production budget, you need a real point of view. Here are ten formats worth building into your content mix.

01 A contrarian take

Pick a belief your industry treats as settled and argue the other side, backed by your own reasoning — not just for the sake of disagreement.

02 A customer win, told specifically

Share a specific result with real numbers wherever you can. If you can't name the client, describe the situation and outcome generically — specific beats vague either way.

03 A "how we do it" process breakdown

Walk through the exact steps behind one part of how your team actually works — the more concrete and specific, the more it reads as expertise rather than marketing copy.

04 A hiring or culture post

Share an open role along with what a normal day in that job actually looks like — these consistently pull strong comments from both candidates and peers.

05 A data or trend commentary post

React to a real, recent industry data point or platform change with your own take on what it means for the reader's business, not just a restatement of the news.

06 A poll on a genuine dilemma

Ask an either/or question your audience is actively deciding right now — polls work because voting is a low-effort way for LinkedIn to register real engagement.

07 A carousel breaking down a framework

Turn a checklist or process into a native document post with one idea per page — this format tends to earn longer dwell time than a single image.

08 A founder or leader personal story

Tell one specific moment plainly — a mistake, a turning point, a hard decision — rather than a polished highlight reel. Specificity is what makes it land.

09 A mistake-and-lesson post

Describe something that didn't work and what actually changed on your team because of it. Admitting a real miss builds more credibility than another win post.

10 A curated industry roundup

Pull together three to five things worth reading or watching this month, each with your own one-line take — the opinion is what makes it worth posting, not the links.

How to run LinkedIn as a paid channel

LinkedIn Campaign Manager groups every objective into three stages: Awareness (Brand Awareness — simple impression-based reach); Consideration (Website Visits, Engagement, Video Views — see our LinkedIn Video Ads guide if that's your format); and Conversion (Lead Generation, using native forms pre-filled with a member's own LinkedIn data, and Website Conversion, tied to a tracked action on your site).

LinkedIn's real differentiator is targeting: job title, seniority, function, company size, company name, industry and skills — a level of B2B precision no other platform in this guide matches. Matched Audiences layers on retargeting for your own website visitors, an uploaded contact or account list, or specific named companies for account-based marketing.

Be honest about cost going in: LinkedIn's CPCs run meaningfully higher than Meta's or X's — the tradeoff for reaching a precisely-targeted professional audience with far less spend wasted on people who were never going to buy. Budget for a longer testing runway than you'd plan on Facebook or Instagram.

Key takeaways: Get the current sizes right (1200×627px for feed images, 1128×191px for a Page cover, 1584×396px for a profile banner) so nothing crops awkwardly. The algorithm rewards early engagement, dwell time and comments over passive likes — and native documents or video tend to travel further than outbound links. For content, specific and slightly contrarian beats polished and generic.

Frequently asked questions

What size should a LinkedIn post image be?

1200×627px (a 1.91:1 ratio) is the standard recommended size for a single-image feed post — it displays without an awkward crop on both desktop and mobile. A square 1:1 image also works cleanly, especially on mobile, where LinkedIn shows more of a square image in the feed than a wide landscape one.

What's the correct LinkedIn company banner size?

A LinkedIn company Page cover banner should be 1128×191px. It sits behind your Page's logo and name, so keep any important text or graphics out of the bottom third of the image, since the info panel overlaps that area on mobile devices.

How does the LinkedIn algorithm decide reach in 2026?

LinkedIn hasn't published an exact formula, but based on its own statements and observed patterns, early engagement in the first 60–90 minutes, dwell time (how long someone actually stays on your post), and comments — weighted above simple reactions — are the strongest known signals. Native formats like documents and video also tend to see more reach than posts linking off-platform.

Do LinkedIn carousels (document posts) still get more reach?

Directionally, yes — native document posts tend to earn longer dwell time than a single static image, since a reader pages through multiple slides instead of glancing once, and LinkedIn's distribution appears to reward that. This is an observed pattern based on how the platform's signals work, not an official, permanently guaranteed algorithm rule, so it's worth tracking on your own page rather than assuming it holds forever.

What kind of LinkedIn posts get the most engagement for B2B brands?

Specific, opinionated content consistently outperforms generic or purely promotional posts — a contrarian take backed by real reasoning, a customer result with actual numbers, a process breakdown, or a founder story told plainly all tend to earn more comments than a polished announcement. Comments matter more than reactions to LinkedIn's algorithm, so content that invites a genuine reply tends to reach further.
